Sound
LilyPond can produce MIDI output. The performance lacks lots of interesting effects, such as swing, articulation, slurring, etc., but it is good enough for proof-hearing the music you have entered. Ties, dynamics and tempo changes are interpreted.
Dynamic marks, crescendi and decrescendi translate into MIDI volume
levels. Dynamic marks translate to a fixed fraction of the available
MIDI volume range, crescendi and decrescendi make the the volume vary
linearly between their two extremities. The fractions be adjusted by
overriding the absolute-volume-alist defined in
scm/midi.scm.
For each type of musical instrument (that MIDI supports), a volume range
can be defined. This gives you basic equalizer control, which can
enhance the quality of the MIDI output remarkably. You can add
instruments and ranges or change the default settings by overriding the
instrument-equalizer-alist defined in scm/midi.scm.
Both loudness controls are combined to produce the final MIDI volume.
BUGS
It is currently not possible to use the percussion channel (generally channel 10 of a MIDI file).
